I have this "AGPtek K-Type SNR PID Temperature Controller" [LINK] and really have an issue, I cannot figure out. The temperature is not reading as I would expect it to. I followed all the steps from dward51 in a thread from about 18 months ago [HERE] and the wiring was super easy and straight forward.
In a ice water bath I am getting a reading of around 210* F, I have confirmed I have the PID controller in F mode, and K type probe setting. Although I cannot get a true temp reading. I even tried to use the offset setting, to display a 180-ish offset on the display, so it would kind of work correctly, but after changing the offset in the PID< its still didn't display the right temp, still just the 210* in the ice water bath.
I tried 2 different probes with this, same result, so I don't think it could be 2 bad probes.
Even with the wrong temps, I can change the SET point to be higher, and the PID turns on the SSR, and below it the PID shuts it off. So I know it is working otherwise. Just getting a horribly off temp reading.
I hope this doesn't mean its a bad unit, I suppose I can just send it back since I got it from Amazon and buy a new, better one. I think I'll order the Auber anyway, even if this one can be remedied.
Anyway, what do you guys think it could be?
